Manchester United want two big money signings before they begin preseason on July 1.
The Red Devils have been linked with numerous targets this summer, with Ole Gunnar Solskjaer looking to completely overhaul his squad after a poor season.
The Sun says United are looking at Ajax's Matthijs De Ligt, Toby Alderweireld, Kalidou Koulibaly and Thomas Meunier in the defender department.
Joao Felix, Bruno Fernandes and Adrien Rabiot are three midfield options available, with the later available on a free.
An Old Trafford source - quoted by The Sun - said: "Some of the staff at Carrington have been told to expect at least two new faces visiting before training on July 1.
"The red carpet is being rolled out to prospective signings and their agents, showing them all we have to offer.
"We are pretty confident a couple are close to getting over the line. Talks are going well and have been before the end of last season.
"There could be as many as four that join up with the rest of the squad in upcoming tour of Australia and Far East."
